Sure, they had to tell, that they like the game, there is no cut off content and the game looks exactly as they wanted. Especially in interviews before the game was released on all platforms and even released earlier than expected. That's unfortunately understandable.
But the logic in Karlachs quest is just wrong. You should look for the fix, but you don't/ cannot, because it is not in the game and then she dies without any help. I have no idea, if they are all blind in Larian.
